SOUND-BOX.

SPECIFICATION forming part of Letters Patent No. 791,595, dated June 6,1905.

Application filed October I, 1903. Serial No. 175,303. I

To all whom it may concern.-

Be it known that I, LOUIS I. VALIQUET, a citizen of the United States ofAmerica, and a resident of the borough of Bronx, city, county, and Stateof New York, have invented certain new and useful Improvements inSound-Boxes, of which the following is a specimember of the sound-boxcasing and at the. same time centering the sound-box-support.

ing arm relatively beneath the horn, so that the various parts are morenearly balanced, more compact, and present a neat and finishedappearance.

The preferred form of apparatus embodying my invention is illustrated inthe accompanying two sheets of drawings, throughout the several views ofwhich like reference-nu merals indicate corresponding parts.

In the drawings, Figure 1 is a sectional view of the sound-box, taken onthe line 8's of Fig. 2. Fig. 2 is a view in rear elevation. Fig. 3 is aview in elevation,showing the soundbox mounted on a talking-machine; andFig. 4 is a cross-sectional view thereof, taken on the line 8 s of Fig.3.

Referring to the drawings, 1 represents the front or annular member ofthe sound-box casing, the same being internally flanged to provide aseat 2 for the diaphragm 3, which is mounted thereon between gaskets 44:, of rubber or other material, in the usual manner. The stylus-arm 5has one end waxed or otherwise phonetically connected to the diaphragmand the opposite end socketed to receive the needle 6, which is securedtherein by the setscrew 6. The stylus-arm is fulcrumed in the ringmember of the casing to vibrate in the usual manner in opposition to aretractile or centering spring. (Not shown.)

The rear member or back of the casing? is flanged, as at 8, to form atelescoping connection with the front member and is cast in one piecewith a tubular elbow 9, which is split at its outer end and providedwith a setscrew 10, working in lugs 11, to serve as a clamp in securinga horn or trumpet 12 in position. The members of the sound-box casingare secured together by screws 13 13. (Shown in Fig. 2 and indicated bydotted lines in Fig. 1.) An opening or socket 14: and setscrew 15 arealso provided in the back member to receive and clamp the free end of arod 16. which supports both the sound-box and lower end of the horn.This rod is connected by a universal joint 17 with a fixedsupporting-arm 18, extending outward from the motor-box 19 of themachine.

In use the sound-box is mounted on the free end of the rod 16, which issquared or otherwise formed to fit into the socketor opening 14 thereofand is secured by the set-screw 15. The horn is connected by having aterminal nipple thereof clamped in the tubular elbow extension of thesound-box casing and is centered above the supporting-arm 18 and the rod16 in an approximately Y-shaped rest 16.

In operation, as the diaphragm vibrates under the action of thestylus-arm, &c., such vibrations are transmitted by the body of air inthe chambers in the rear of the diaphragm to the column of air withinthe horn.

Some of the main advantages of my invention are as follows: By havingthe elbow connected directly with the casing of the soundbox the partsare-simplified and the soundconducting passage made much more even anduniform throughout its length. The parts are also much more definitelyand securely held in position and balanced, while at the same time thearrangement allows quick and free adjustment, thereby insuring greateraccuracy in the placing of the sound-box and the stylusbar in theiroperative positions.

It will be understood that I do not wish to limit myself to the exactdetail construction and arrangement shown, as various changes may bemade without departing from the spirit and scope of my invention. Allsuch changes, however, I consider obvious and immaterial variations ofform and not of substance and still within the meaning of thepresentinvention.

Having, therefore, described my invention, I claim Y 1. In a sound-boxfor talking-machines, a casing, an elbow rigidly connected thereto, theouter end of said elbow being split and means for drawing the splitportions of said elbow together.

2. In a sound-box for talking-machines, a casing, an elbow rigidlyconnected thereto, means for clamping the outer end of said elbow aboutthe end of an amplifying-horn and a socket also carried by said casingand adapted to adjustably receive the end of the soundboX-supportingarm.

3. In a sound-box for talking-machines, a

casing, an elbow integrally connected thereto, means for clamping theouter end of said elbow about the end of an amplifying-horn, anindependent socket carried by said sound-box adapted to adjustablyreceive the end of the sound-boX-supporting arm.

4. In a sound-box for talking-machines, the combination with a casinghaving an integral elbow, means for clamping said elbow about the end ofan amplifying-horn or other soundconveying means, an integral projectionalso carried by said casing having an opening therein adapted to receivethe sound-box-supporting arm and means for adjustably clamping said armwithin said opening.

Signed at New York, N. Y., this 21st day of September 1903.
